Using Dual SIM devices
If you are using a Dual SIM device, it works with either one or two SIM cards inserted. You can get incoming communication to both SIM cards and select which number to place outgoing communication from. Before using multiple SIM cards, you need to enable them and select a SIM card which will handle data traffic.
You can forward calls that come in on SIM 1 to SIM 2 when SIM 1 is unreachable, and vice versa. This function is called Dual SIM reachability. You must enable it manually. See Forwarding calls.
